PCThat's awesome.  Great collection.
But why stop there?  You can use your existing collection as the base of a HOF type card collection.  In my mind that would be perhaps the ultimate collection -- one of every HOFer, with an example from every set. 
Actually, leaving aside the super-expensive and one of a kind cards, the ultimate collection would be the earliest example of every HOFer (the proverbial HOF rookie card collection), coupled with HOF type cards.
